Overview

  • The patient represents Wisconsin’s first confirmed measles case of 2026.
  • The Wisconsin Department of Health Services and Waukesha County Health and Human Services are leading the investigation and contact notifications.
  • Measles can remain airborne for up to two hours and may infect up to 90% of unvaccinated people who are exposed.
  • Symptoms typically appear 10 to 21 days after exposure, beginning with fever, cough and red eyes before a spreading rash.
  • Two doses of the MMR vaccine provide about 97% protection, and residents can verify vaccination through the Wisconsin Immunization Registry or their health care provider.
